Scenario

You have more than one Skype account and need to be able to login to both accounts simultaneously.

Solution

Navigate to the Skype folder. Usually something like: C:\Program Files\Skype\Phone

Right click on Skype.exe > Click Create shortcut. If necessary save the shortcut to the Desktop

Right click on the newly created shortcut > Click Rename and give the shortcut an appropriate name (e.g. Personal)

Once again right click on the shortcut > Click Properties and enter the following into the Target field, changing USERNAME and PASSWORD for your Skype username and password:"C:\Program Files\Skype\Phone\Skype.exe" /secondary /nosplash /username=USERNAME /password=PASSWORD /legacylogin
***Note – Make sure this is pasted without any line breaks
/legacylogin is only necessary for Windows XP and Vista

Change the Run field to Minimized

Click Apply and then Click OK

Repeat the process above for any other Skype accounts you have

Finally, right click on each of the shortcuts created and Click Pin to Taskbar
